To all whom it may concern:

Be it known that I, REINHQLD H. WAPPLER, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented an Improvement in Interrupter Apparatus, ol

' which thefollowing is a specification.

Heretofore in the production of the so-called Tesla currents, an apparatus has been employed commonly comprising a spark coil,-an armature mounted to re volveon a suitable axle, the axle being provided with a fiattenedportion'or cam,s. spring, a pair of contact employed to produce the Tesla currents.

points, one being carried by the said spring which is actuated by the flattened portion of the said axle so that the contact points are separated by this flattened portion of the axle and brought together by the action of the spring, arid a. condenser which is charged by the sparks resulting from the breaking of the current at the contact points,the dischargesoi the condenser being fore in X-ray apparatus, for instance an electrolytic interrupter has commonly been employed, but I have found that by suitably arranging the circuits, a mechanical interrupter similar to that hereinbeiore rel'crrcd to in the prodnction of the so-called Tesla currents,-may

be employed with equally efiicient results in an X-ru-y apparatus. In carrying out my invention therefore, i

- employ together with a suitable source of electricity, a

Fig. 3 is a plan of the same, and Fig. 4 is an elevation of a modified lorm of armature. Referring to the drawing, and particularly to Figs. 2 and 3,a designates a base provided at both ends with an upright b journaled in and extending bctwccn which is a shaft or axle c. Secured in this uxlc c is an arms.- ture d and preferably a fly-wheel d, and a portion of the axle c on opposite sides thereof may be flat toned as indicatodat 2.

' 0 represents an upright through which and at right angles to the shn-[t c an adjusting scrcw. c pusscs, thc end 3 of which forms onc oi the contact points at which an picctric circuit may be broken, thc other comuct point 4 being curried on a. suitable spring psi-cured to a block lixcd on the basc or othcrwisc and :ulaptcd lo bc engaged by tho flattcnod portion of thc axlo c to scpnrate the contzict points 3-'l, which return. and contuct with one another by tho action ol thc spring whcn the mile 0 is in it position ut 90 to that shown in tho drowing. i

Now hereto- It will be-understood that a mechanical interrupter other than that hereinbei'orc described, may be em ployed without departing from the nature and spirit of my invention.

Referring particularly to Fig. l, in which the mechanical interrupter is shown together with the other parts diagmimnatically, h is an electro-inagnet so placed that the core thereof is in alinement with the armature d at two points in its revolution.

11 is the customary Rurnkorff coil employed in X-ray apparatus, l a condenser and 'm. a suitable generator or other source of electricity; the positive terminal of the generator in is connected through a suitable resistance m with one terminal of the primary winding of the Ruhmkorfl coil by the wire 5 an d the other end of the primary winding of the Ruhmkorff coil by the wire or connection 6 to the binding post 7 in electrical connec tion with the spring 9 and contact point 4-, the contact point 3 being connected to the negative terminal of the generator through the binding post 8 and wire 9.

From a junction point 10in the wire 5, the wire ll is taken and connected with one terminal of the coil of the electro-rnagnet h, the other end of the magnet coil bding connected by a wire 12 with a binding post 7, while the condenser l is connected across the contact points 3, 4 by the wires l3, 14, leading from its respective terminulsto the binding posts 7, 8, it being understood that the wires 15 from the terminals of the secondury windiiig of the Ruhmkorif coil 71 lead to the terminals ol' the vacuum tube, as is customary in X-ray apparatus. I 1

From the hercinbefore described arrangement of the devices comprisingthe X-ray apparatus, it will be understood that the elcctro-megnet hand the primary winding of the Ruhmkorfi coilnre in multiple wi't-h one another and are both in series with the circuit through the contact points 3, 4, by means of which the circuit is interrupted. Now with the parts in the position the same is energized and imports an impulse to the armature d tending to turn thesume to the position 1 shown in Fig. l, but beiorc reaching this position the contacts' 4 are parted again through the cum action of the flattened portion of the axle against 1hrspringg und the momentum of the urinoiure curries the some over [he nnignetic dcud center position shown in'tho drowing. When the circuit is closed ihrough the magnet coil l1, it will :ilso be closed in multiple therewith through the primary of th Ruhmkorfi coil 2' thereby setting up an induced current in'the secondary oi the Ruhmkorff coil which is utilized by being discharged through a vacuum tube in Xwray work or otherwise as .5. desired. Now as will be understood when the circuit throughthe primary of the Ruhmkorfi' coil is closed --there will be a self induced current set up therein,

which in View of the connections and circuits hereinbefore described wilhbe discharged through the magnet coil h, energizing the same and thereby imparting an additional impulse to the armature d which increases-the rapidity with which the same and the axle c revolve. The condenser l is employed as is customary, to absorb or reduce far as possible, the sparking between the contact points 3 4 in the breaking of the circuit. I v

I have found that the hereinbeiore described straight bar two pole armature d is particularly adapted to low voltage Work, say 10 volts or therealmuts, while at higher voltages-110 volts or thereabouts,-a three pole armature (2 as shown in Fig. 4, may be employed to advantage.

it: being understood that in a given case thearinature z shaftis provided with as many fiat; sides against which the Contact spring operates, as there are poles in the armature employed.

I claim as my invention:

1. In an interrupter apparatus, a source of electricity,

This manifestly is due to the tact, that with the two pole armature, the period of make and. break and consequentlythat of magnetization and dea pair of separable contacts, a revoluble means by which said contacts are separated, an electro magnet, means actuated by the electro magnet for operating the means for separating the contacts, a mechanical means for bringing the contacts together and a Ruhmkorlf coil in circuit in multiple with the said electro magnet.

2. in an interrupter apparatus, a source of electricity. a pair of contacts, terminals therefor, a magnet. means operated thereby for separating said contacts and :1 ltuhnr kortf coil whose primary winding is in multiple with the coil of the said magnet: between the said source of electricity and the terminal of one of the said contacts, so that the coil of the magnet and the primary of the said lluhmkorfilcoil are in multiple with each other when the circuit is closed by the said contacts and the coil of the.

said magnet and the primary of the said lluhmkorilf' coil are in series with each other when the cirenir is broken at the said contacts.
